Abstract: Foil bags are used as a primary packaging for liquids, the bags permitting the liquid to be taken therefrom without the application of a considerable amount of force. A container is provided for a medicinal liquid, the container being gas-tight and liquid-tight so that it is storable over many months. The container includes a collapsible foil bag on which a flange, which is stable in respect of shape, is disposed. The flange is designed for fitting onto a discharge connection member. The container can be disposed in a casing which is stable in respect of shape. The medicinal liquid does not come into contact with air and is protected from the effect of light. The medicinal liquid may be dispensed from the foil bag in many partial quantities over a prolonged period of time, with a respective partial amount thereof being converted into an aerosol by means of an atomizer.

Abstract: The present invention relates to a piston pumping system for substantially gas-free measurement and/or pumping of predetermined quantities of liquids, preferably pharmaceutical liquids containing oxidation-prone ingredients. Preferably, the system is used as a micropump or as a component thereof in medical devices such as transdermal therapeutic systems, for example.

Abstract: A miniaturized device for pressurizing fluid. The device includes a hollow piston that provides a fluid path and a valve member. The valve member is configured for axial movement so that the valve axis remains parallel to the piston axis. The valve member is arranged at one end of the hollow piston. The valve member may be partially or completely disposed within the hollow piston. The device is particularly adapted for use in a mechanically operated atomizer to produce an inhalable aerosol of a liquid medicament without the use of propellant gas.

Abstract: Needle-less injectors for liquids are known in many different forms which are adapted to different conditions of use. The needle-less injector according to the invention is in the form of a hand-held unit. It includes a locking stressing mechanism, an energy-storing spring (36), a hollow plunger (37) displaceable in a cylinder (38) and a nozzle (39). At its one end, the hollow plunger is provided with a valve body (42). The supply container (44) for the liquid is arranged within the housing. When the locking stressing mechanism is stressed by rotation of the two housing portions (31, 32) relative to each other the hollow plunger (37) is drawn out of the cylinder (38); at the same time the amount of liquid required for an injection is conveyed out of the supply container (44) through the plunger into the pump chamber (43). After the locking stressing mechanism is triggered the amount of liquid is expelled from the pump chamber through the nozzle.

Abstract: The invention relates to a nozzle system for a delivery device for liquids, wherein the nozzle system comprises a nozzle and a device which fixes the nozzle in the delivery device. The delivery device, an atomiser, has a liquid reservoir from which a liquid is forced through the nozzle under pressure. The nozzle fixing means may itself be secured by a second fixing, e.g., in the form of a check nut, or the fixing may itself be a check nut. According to the invention the fixing means on the nozzle outlet side has a specific geometry which minimises the proportion of dispensed liquid deposited on the fixing means.

Abstract: For the withdrawal of a liquid from a closed container which is in a fluctuating position in space in a portable piece of equipment, precautions are to be taken so that the liquid can be withdrawn as completely as possible and in a trouble-free manner. A closed container is provided with an open-pore porous storage medium which is in the form of an integral body. It preferably fills only a part of the container, it is disposed at least in the region of the end of the withdrawal connection portion, and it touches the liquid at least at times. The storage medium serves as a pre-storage means for the liquid and as a bubble barrier. It constantly holds a certain amount of the liquid in the proximity of the end of the withdrawal connection portion, even if the end thereof is above the level of liquid in the container.

Abstract: The mounting of a component subjected to pressure from a fluid requires special precautions if the component is made of wear resistant, hard and hence generally brittle material and may be destroyed by locally raised stresses. A fluidic component of this kind, made, for example, of silicon/glass is arranged in an elastomeric shaped component, made, for example, of silicon rubber. The inner contours of the elastomeric shaped component correspond to the outer contours of the fluidic component. The outer contours of the shaped component corresponds to the inner contours of a holder. Due to this “floating mounting” there are no unacceptable local pressure peaks and no deformation of the fluidic component. The device is particularly suitable for mounting a fluidic component made of glass or silicon, or miniature dimensions, subject to high pressure.
